What Alkios does

Alkios, legally organized as HOLDING EGILOPE (a privately held French SAS registered in Avignon), is an ecosystem of 7 wholly-owned environmental consulting subsidiaries created in 2016 to unify firms whose first entity dates to 1992. The company provides multidisciplinary environmental, biodiversity, and ecological engineering services, including wildlife and flora inventories, biodiversity assessments, environmental impact studies, urban ecology, wetland and nature-based solutions, GIS mapping, contaminated sites remediation, project management, and regulatory filings. Its 7 operating subsidiaries — AGE (Antilles Guyane Environnement), Ekos Ingénierie, Ekores, Naturalia Environnement, OGE (Office de Génie Ecologique), Synactile, and AEPE-Ginkgo — cover complementary specializations such as CSR consulting, ecological engineering, training on living organisms, and landscape/natural spaces planning. Alkios serves two primary verticals: territories and local governments (climate adaptation, environmental compliance, sustainable development planning) and companies/corporations (RSE/CSR strategy, carbon footprint reduction, environmental certification, employer branding), with named customers including Vinci Autoroutes and Conseil Départemental de la Sarthe.

The underlying technology stack is domain-specialized rather than software-centric: Alkios employs proprietary methodologies including eDNA (environmental DNA) species inventories, soil life assessments, acoustic measurements, and international scientific expeditions, supported by 150+ scientific publications and 4 scientific awards for research and innovation. There is no public API, SDK, or platform product; the offering is delivered as professional services rather than licensed technology. The firm operates 17 locations across metropolitan France plus French overseas territories (French Guiana, Antilles, New Caledonia), and is a strategic member of Alliance Vigilife, a global observatory of living beings.

Alkios monetizes exclusively through professional services — direct consulting engagements sold to enterprise and government clients on a quote-based model covering the full project lifecycle from diagnosis through evaluation. Go-to-market is sales-led and direct, with no disclosed channel partner or reseller network. Marketing is primarily top-of-funnel: a multilingual corporate website (French, English, Spanish), a LinkedIn corporate page, blog/news content, and mid-funnel webinars (e.g., the "Human Ecology" series). Revenue is not publicly disclosed, and the company has no known external institutional investors or private equity backing, retaining founder/president Benjamin Allegrini as the principal architect of the ecosystem.
